No, this doesn't mean anything. Interface versions are different from
the software versions. For instance, otool says for neon:

        /opt/local/lib/libneon.26.dylib (compatibility version 27.0.0, current version 27.3.0)

while the library files are:

  /opt/local/lib/libneon.26.dylib -> libneon.26.0.3.dylib
  /opt/local/lib/libneon.dylib -> libneon.26.0.3.dylib

Here you can see that there are no relations between interface
versions (27.0.0, 27.3.0) and the library version (0.26.3). And
software linked with /opt/local/lib/libneon.26.dylib (such as
svn) will continue to work when neon is upgraded if the interface
is compatible: /opt/local/lib/libneon.26.dylib will point to a
new file, but that's not a problem.

The problem with readline is somewhere else. It should be fixed
so that software is linked to /opt/local/lib/libreadline.5.dylib
instead of /opt/local/lib/libreadline.5.*.dylib.
